Tragopogon mirus Ownbey, the remarkable goatsbeard, is a species considered native to certain regions of North America. Intensive studies over the course of many years have demonstrated that it originated as an allopolyploid hybrid between T. dubius Scop. and T. porrifolius L., both of which are European species naturalized in the US. Tragopogon mirus has become established in the wild, reproducing by its own, thus deserving recognition as a species.
